That's it!
I switch my computer with another guy on here, so I could put my car back to stock.
I had a Jet.t chipped ecu. He had a stock
I'm almost 100% sure that he shafted me.
After about 4 days of having the new computer the idle started going down and down, and now i had to screw the throttle stop out so that its like I'm pushing the gas a little,
Afm. Perfect,
Iac, replaced and still same symptoms
Dropped exhaust for maybe clog ,nope
Spark plugs? No
Tps? Perfect

Is there anything else that will cause a 1uzfe to not idle?

And is there anybody in the pittsburgh area that would let me borrow their ecu for an afternoon
Or anybody local who would have suggestions?

Thanks

Check your vacuum lines.

 

oh yeah, clean your intake throttle body. Any black residual will cause a little problem

 

Which ones and what I'm I seeing what they do?
Should I check for suction?

 

Yes check for suction or cracks. If you think they need to be replaced, then replace them. Its cheap insurance. Check all of them. There is two that goes under the actual intake. Spray carb cleaner on the motor while its running, and see if the idle raises or lowers, then go from there. Clean the intake of the throttle body with carb cleaner. Make sure to use a new gasket.

 

Use a smoke machine and run a smoke test to look for air leaks in the manifold and vacuum lines. O2 sensors are a common come and go item that the SC eats for breakfast. You might wanna check those for voltage. Make sure your gasoline is clean by running a tube of injector cleaner throught the tank. In fact, do that just for grins. It probably needs it if it hasn't been done in a while.

 

or just use a cigarette :P

 

I'm confused on the smoke test idea, how do u test if a vacuumed leak is it? I really want to try a new computer. I'm so worked up about this car

 

Smoke is done by a mechanic who has the machine. It is injected in the motor and where the smoke appears thats the leak. Easy and eliminates any probability.

 

Oh so through the intake tube,

Wish I knew a mechanic who had a smoke machine
